Design of optimal topology for engineering products subject to mechanical loads has been traditionally approached through homogenization and more recently through introducing constraints on perimeter to ensure well-posedness.This paper reports attempts to obtain numerical solution to the problem of maximization of stiffness by distributing a given material in a discretized domain,with constraints on perimeter and appearance of small chattering voids,using Genetic Algorithm.Convergence of the numerical procedure is established and detailed topologies are obtained for various values of volume constraints.
